Is Israel's Iron Dome missile defense system ironclad?_我的网站

一 |     新加坡的钱币兑换商不只令吉热续，近来人民币也掀热潮。（新明日报图） （新加坡讯）新元兑令吉从上月1比3.45降至1比3.33，有人赶紧将新元兑成令吉，但有不少马来西亚游子观望中。    JERUSALEM -- Since Israel activated the Iron Dome in 2011, the cutting-edge rocket-defense system has intercepted thousands of rockets fired from the Gaza Strip.The system has given residents a sense of security, and Israelis can often be seen watching the projectiles flying through the skies and destroying their targets overhead.But the current war with Hamas might be its stiffest challenge yet.In just two weeks, Hamas has fired 7,000 rockets toward Israel, according to the Israeli military. That is more than any of the previous four wars fought between Israel and Hamas since the militant group seized power in Gaza in 2007. On Oct. 7 alone, the first day of fighting, Hamas launched at least 2,000 rockets, according to data from West Point. Lebanon's Hezbollah has also fired hundreds of rockets along Israel's northern front since the fighting began.Most of the rockets have been intercepted. But some have managed to get through, killing at least 11 people and hitting buildings as far away as Tel Aviv, according to Israeli officials.Here is a look at the accomplishments — and limitations — of the Iron Dome.The Iron Dome is a series of batteries that use radars to detect incoming short-range rockets and intercept them.Each battery has three or four launchers, 20 missiles, and a radar, according to Raytheon, the U.S. defense giant that co-produces the system with Israel's Rafael Defense Systems.Once the radar detects a rocket, the system determines whether the rocket is headed toward a populated area. If so, it launches a missile to intercept and destroy the rocket. If the system determines the rocket is headed to an open area or into the sea, it is allowed to land, thus conserving missiles. According to the military, all interceptions occur in Israeli airspace.The military declined to comment on how many Iron Dome batteries are currently deployed. But as of 2021, Israel had 10 batteries scattered around the country, each able to defend a territory of 60 square miles (155 square kilometers), according to Raytheon. It is roughly 90% effective, according to Rafael.But it can get overwhelmed if a mass barrage of rockets is fired, allowing some to slip through. While it has performed well so far, the risk could be raised if Hezbollah enters the war. Hezbollah has an estimated 150,000 rockets and missiles.Each missile costs an estimated $40,000 to $50,000, according to the Institute for National Security Studies, a Tel Aviv think tank.The U.S. has invested heavily in the system, helping with development costs and replenishing it during times of fighting.President Joe Biden has said he will ask Congress for $14.3 billion in military aid for Israel. The majority of that would help with air and missile defense systems, according to the White House.“We’re surging additional military assistance, including ammunition and interceptors to replenish Iron Dome,” Biden said.___Find more of AP’s coverage at https://apnews.com/hub/israel-hamas-war。牛车水珍珠一家钱币兑换商的合伙人黄素珍对《新明日报》说，尽管令吉增值，依旧有不少人兑换令吉。“其实反而越多人换，因为大家会担心下来跌更多。

二 | 上个月还有1新元兑3.45令吉，这周就变1比3.33，我们不用说太多，顾客心里都有数。相比2019年8月的1比2.99兑换率，现在的兑换率还不错。”不过，她认为新元强劲，令吉兑换率应该不会跌到3以下，不过，要到中秋了，到时预计会有不少游子换令吉过节。来新工作的冯胜宽（24岁，文字工作者），平均每个月会兑换一次令吉。“虽然我觉得不会跌破3，但还是要再观察，趁兑换率还有3先换，反正都要用。我还打算进新山买月饼，所以下周会先兑换200新元。”雅吉拱廊的兑换商的前天新元兑令吉的兑换率，介于1比3.33至3.342。昨早银行间汇率是1比3.36，电子钱包则可换到3.35。

三 |     新元兑人民币突破1比5.4，创最高记录引兑换热，前天涨至1新元兑5.47人民币。莱佛士区内至少4家兑换商前午缺货，另有业者上半天就卖出40万人民币。数据显示，新元兑人民币的银行间汇率自7月11日突破1比5.4，之后虽偶有下跌至1比5.3，但基本上呈上升趋势，前天涨至1新元兑5.47人民币，创历史新高。记者前午走访莱佛士地铁站外的雅吉拱廊（The Arcade），发现至少四家钱币兑换商挂上人民币缺货的标注。据观察，雅吉拱廊有至少10家实体兑换商，各家新元换人民币的兑换率大致上介于1新元兑5.345至5.42人民币。一名不愿透露姓名的兑换商受访说：“上周就有新元兑人民币1比5.4的兑换率，不少顾客来换人民币，大几千元的换。

四 | 这两天好几家缺货，我们只有一点存货，暂时标注没货。”牛车水珍珠坊的钱币兑换商合伙人黄素珍也说，这两周生意增加了20%，昨天截至下午3时已卖出40万人民币。

五 | 此外，她也分析了人民币持续疲弱的原因。“中国是生产国家，货币便宜，才能增加产出和竞争力，进而提高经济增长。然后就是最近新加坡经济增长率调高，而中国经济增长率又低于预期，加上美联储利率，这些都可能影响人民币的兑换率。
